BEWARE OF SAMSUNG TV NEW MODEL TV AUDIO ISSUES IT DOES NOT HOLD THE AUDIO

OMG THIS SAMSUNG NEW MODEL NU7100 JUST KEEPS GETTING WORSE AND WORSE. IT IS NOT SOPHISTICATED ENOUGH TO HOLD THE CORRECT AUDIO SETTINGS SO WHEN WE ARE USING OPTICAL FIBRE CONNECTION FOR SOUND AND YOU SWITCH THE TV OFF AND THEN ON AGAIN IT LOSES THE SOUND AND THEN WE HAVE TO GO INTO EXPERT SETTINGS TO RESET EVERYTHING EVERY TIME WE SWITCH THIS TV ON. THIS IS CRAZY AND SICK THAT WE HAVE TO GO THROUGH THIS. AND WHEN I WAS CALLED BY SAMSUNG THEIR RESPONSE WAS : OH JUST RATHER USE HDMI SETTINGS AS THE TV CAN'T HANDLE THE OTHER SETTING. *** ???????
